Tor-ramdisk is an i686 uClibc-based micro Linux distribution whose only purpose is to host a Tor server in an environment that maximizes security and privacy. Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. Security is enhanced by employing a monolithically compiled GRSEC/PAX patched kernel and hardened system tools. Privacy is enhanced by turning off logging at all levels so that even the Tor operator only has access to minimal information. Finally, since everything runs in ephemeral memory, no information survives a reboot, except for the Tor configuration file and the private RSA key which may be exported/imported by FTP. MIPS version.

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).

Authors: George DanezisTags: privacyEvent: Chaos Communication Congress 21th (21C3) 2004Abstract: We will present the state of the art in deployed anonymous communication systems, and in particular Mixminion, for anonymous email, and Tor, for anonymous web browsing. We will focus on the concrete future challenges to deploy and strengthen theses systems. In the last few years there has been a renewed interest in anonymous communications, both in terms of accademic work but most importantly in terms of implemented and deployed systems. This talk will be geared towards those at the cross section of practice and reaserch that are interested in developing or strengthening applications that provide some anonymity protection. We will describe two systems that are based on solid theoretical work, and should provide a high degree of security: Mixminion, is a high latency remailer, that can be used to anonymise email, while Tor is a low latency Onion Router, supporting the transport of any TCP stream. The two architectures are complementary, and provide very different security properties. While deployed, for testing, they Mixminion and Tor are both works in progress, and many practical as well as research challenges need to be resolved before they become widely used. The talk will first give an overview of Mixminion and Tor, highlight their architectural similarities and differences. Some attention will be paid to the threat models that they try to protect against and the features that they provide. The key attack techniques will be presented, but without going into the mathematical details. Pointers for further reading will be provided for those who are keen. Then we shall focus on the issues that remain to be resolved to widely deploy these systems, and further strengthen them. These issues are both research questions or concern the practical implemetation of anonymous infrastructure and services. On the one hand there is a need to build more services merely to support anonymous communications: from the implementation of pseudonym servers, directory services, or integration into client applications to research on DoS prevention and flooding. On the other hand the communication infrastructure is only there to be used by higher level applications. Therefore there is a need to understand which applications can be used without modifications over anonymous communications, and which will require to be modified not to compromise identity information. As a result of this talk participants should feel confortable with the basic design of anonymity systems, and know where to find additional information to use or build on these systems. If they choose to further look into the subject they will know what the main issues are where more work is required, and know the venues where this work can be presented, used, and appreciated.

I'll talk about design decisions, some everyday uses for anonymity networks, and where we need to go from here. Tor (second-generation Onion Routing) is a distributed overlay network that anonymizes TCP-based applications like web browsing, secure shell, and instant messaging. We have a deployed network of 50 nodes in the US and Europe, and the code is released unencumbered as free software. Tor's rendezvous point design enables location-hidden services -- users can run a standard webserver or other service without revealing its IP. I'll give an overview of the Tor architecture, and talk about why you'd want to use it, what security it provides, and how user applications interface to it. I'll show a working Tor network, and invite the audience to connect to it and use it.

Authors: Alan BradleyTags: reverse engineeringrootkitEvent: Chaos Communication Congress 23th (23C3) 2006Abstract: This talk will cover two rootkits used as reverse engineering tools, one rootkit support library, one IDA plugin, and talk setup material. The talk itself will be given over VOIP and VNC running over the Tor network to demonstrate a proof of concept on anonymous public speech. This talk will present Tron, an extension of the Shadow Walker memory cloaker technique. Tron is a kernel driver who can cloak userland memory, and provides an API that allows the user to cloak arbitrary process memory, set permissions, signal changes of trust, conceal DLLs, and read/write hidden memory. An accompanying IDA plugin that uses this API to conceal software breakpoints will be discussed, and Another Debugger Hiding Driver, or ADHD will be presented as well. While these tools have many legitimate uses from malware analysis to legal reverse engineering and program modding, it is possible that Tron in particular can be used as a component of a "copyright circumvention device", which renders it prohibited by the USA DMCA. For this reason, but more so out of a desire to demonstrate a "proof of concept" for how to anonymously speak publicly, the speaker will be giving the talk over VOIP and VNC relayed through the Tor network. In addition to taking questions over VOIP, the speaker will also be briefly available on IRC afterwords for questions + discussion about Tron, reverse engineering, and the speech setup.

Authors: Steven J. MurdochTags: hardware hackingEvent: Chaos Communication Congress 23th (23C3) 2006Abstract: By requesting timestamps from a computer, a remote adversary can find out the precise speed of its system clock. As each clock crystal is slightly different, and varies with temperature, this can act as a fingerprint of the computer and its location. The end of my 22C3 talk showed how a side effect of TCP/IP steganography detection was to precisely measure the error of a computers system clock (skew). This talk will review and expand on that material, showing the various other mechanisms for monitoring clock skew and discussing the tradeoffs involved. Because every computer has a unique clock skew, even ones of the same model, this acts as a fingerprint. Even if that computer moves location and changes ISP, it can be later identified through this clock skew. In addition to varying between computers, clock skew also changes depending on temperature. Thus a remote attacker, monitoring timestamps, can make an estimate of a computers environment, which has wide-scale implications on security and privacy. Through measuring day length and time-zone, the location of a computer could be estimated, which is a particular concern with anonymity networks and VPNs. Local temperature changes caused by air-conditioning or movements of people can identify whether two machines are in the location, or even are virtual machines on one server. The temperature of a computer can also be influenced by CPU load, so opening up a low-bandwidth covert channel. This could be used by processes which are prohibited from communicating for confidentiality reasons and because this is a physical covert channel, it can even cross "air-gap" security boundaries. The talk will demonstrate how to use this channel to attack the hidden service feature offered by the Tor anonymity system. Here, an attacker can repeatedly access a hidden service, increasing CPU load and inducing a temperature change. This will affect clock skew, which the attacker can monitor on all candidate Tor servers. When there is a match between the load pattern and the clock skew, the attacker has linked the real IP address of a hidden server to its pseudonym, violating the anonymity properties Tor is designed to provide. The talk will also present a separate illustration of the temperature covert channel technique, investigating a suspected attack on the Tor network in August 2006, by a well equipped adversary.

Authors: Steven J. MurdochTags: hardware hackingEvent: Chaos Communication Congress 23th (23C3) 2006Abstract: By requesting timestamps from a computer, a remote adversary can find out the precise speed of its system clock. As each clock crystal is slightly different, and varies with temperature, this can act as a fingerprint of the computer and its location. The end of my 22C3 talk showed how a side effect of TCP/IP steganography detection was to precisely measure the error of a computers system clock (skew). This talk will review and expand on that material, showing the various other mechanisms for monitoring clock skew and discussing the tradeoffs involved. Because every computer has a unique clock skew, even ones of the same model, this acts as a fingerprint. Even if that computer moves location and changes ISP, it can be later identified through this clock skew. In addition to varying between computers, clock skew also changes depending on temperature. Thus a remote attacker, monitoring timestamps, can make an estimate of a computers environment, which has wide-scale implications on security and privacy. Through measuring day length and time-zone, the location of a computer could be estimated, which is a particular concern with anonymity networks and VPNs.

Authors: Roger DingledineTags: TorEvent: Chaos Communication Congress 24th (24C3) 2007Abstract: Come talk with Roger Dingledine, Tor project leader, about some of the challenges in the anonymity world. How do we get enough users? How do we get enough servers? How does public perception impact the level of anonymity a system can provide? How should we be interacting with law enforcement? How can we patch Wikipedia so it no longer needs to fear anonymous users -- or can we do it without changing Wikipedia at all? Can we protect Tor users who want to keep running their active content plugins? When are we going to see well-documented and well-analyzed LiveCD, USB, virtual machine, and wireless router images for easier and safer deployment? Should Tor switch to transporting IP packets, or should it continue to work at the TCP layer? How do we scale the directory system while handling heterogeneous and unreliable nodes, and without sacrificing security? Are three-hop paths really still better than two hops? What are the performance/legal/security tradeoffs of caching content at the exit nodes? Are padding and traffic shaping still bad ideas? Why aren't more people using hidden services and censorship-resistant publishing? Is everybody comfortable with having corporate and government users on the same network? How's it going with China and Saudi Arabia? What development projects does The Tor Project need your help with? Roger will give you his best answers for some of these topics and more, but you are encouraged to bring your own questions too.

Authors: Jens KubiezielTags: privacyEvent: Chaos Communication Congress 24th (24C3) 2007Abstract: I2P is a message-based anonymizing network. It builds a virtual network between the communication endpoints. This talk will introduce the technical details of I2P and show some exemplary applications. I2P has a different approach than most other known anonymous applications. Maybe you know about the anonymisation network Tor. Here you have central directory servers, onion routers (relaying traffic), onion proxies (send and receive data from the user) and other software roles within the network. I2P calls every software a router and it can send and receive data for the user as well as relay traffic for other users. Furthermore I2P uses no central server for distributing information about routers. You'll get the information from I2P's network database. This is a pair of algorithms which share the network metadata. The routers participate in the Kademlia algorithm. It is derived from distributed hash table. My talk will tell you in detail how I2P work, what roles routers, gateways, netDb etc. plays. Furthermore I'll show differences and similarities to other anonymizing networks e. g. Tor and introduce some exemplary applications.

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. Security is enhanced by employing a monolithically compiled GRSEC/PAX patched kernel and hardened system tools. Privacy is enhanced by turning off logging at all levels so that even the Tor operator only has access to minimal information. Finally, since everything runs in ephemeral memory, no information survives a reboot, except for the Tor configuration file and the private RSA key which may be exported/imported by FTP. x86 version.

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).

Authors: Roger DingledineTags: vulnerabilityTorprivacyEvent: Chaos Communication Congress 25th (25C3) 2008Abstract: There have been a number of exciting bugs and design flaws in Tor over the years, with effects ranging from complete anonymity compromise to remote code execution. Some of them are our fault, and some are the fault of components (libraries, browsers, operating systems) that we trusted. Further, the academic research community has been coming up with increasingly esoteric – and increasingly effective! – attacks against all anonymity designs, including Tor.

Authors: Adam ObengTags: TorprivacyEvent: Chaos Communication Congress 27th (27C3) 2010Abstract: The Internet began as state-sponsored anarchy, but it is now the tool of first resort for dissidents and propagandists alike. The poster-child project of the Free Software Movement runs on the authority of a single person; the rest clash over the very definition of the word 'free'. A company which pictured itself as smashing Big Brother is now seen as one of the perceived secretive and authoritarian in the industry; and for another, 'Don't Be Evil' is proving to be a challenging motto to live by. This talk aims to present a view of the societies of Internet from the perspective of political philosophy. Political philosophy is not politics, in the same way that computer science is not programming. It's not the politics about the Internet, but the politics *of* the Internet. Even so, events at any particular place or time just provide examples to be studied. Political philosophy is meta-politics, it's about the trends in politics and the theories we use to understand them. Real-world political systems have striking parallels in the evolution of the Internet: there was primitive anarchy before Eternal September, the era of walled gardens resembled that of Ancient Greek city-states, which were succeeded by more-or-less liberal regimes following the geographical territories of real-world governments. Because of its rapid evolution, mass participation, and highly complex human interaction, the Internet should be subjected to the sorts of questions that political philosophers ask. On the Internet, what is freedom? Do we have obligations to those in control? To each other? What rights do we have? What can we own? Once we know the way it is, we can ask how it should be...

We show how a third-party observer (e. g. proxy server or DNS server) can create a long-term profile of roaming web users using only statistical patterns mined from their web traffic. These patterns are used to track users by linking multiple surfing sessions. Our attack does not rely on cookies or other unique identifiers, but exploits chatacteristic patterns of frequently accessed hosts. We demonstrate that such statistical attacks are practicable and we will also look into basic defense strategies. traffic analysis and fingerprinting attacks on users of anonymizing networks. Even if anonymizeres like Tor are used, a local adversary can measure the volume of transfered data and timing characteristics to e. g. determine the retrieved websites. We will shortly sketch the current state of the art in traffic analysis, which has been improved significantly within the last year

Authors: Eric FiliolSeun OmosowonTags: TorEvent: Chaos Communication Congress 28th (28C3) 2011Abstract: This talk deals with weaknesses identified in the TOR network protocol and cryptography implementation. We manage to take control over users using this network and to access all your information and data exchanged despite cryptography. The TOR network is one of the most famous way to use Internet in a anonymous and secure way at least supposedly. Tor client software routes Internet traffic through a worldwide volunteer network of servers in order to conceal a user's location or usage from someone conducting network surveillance or traffic analysis. Aside protocol-oriented aspects, TOR security relies heavily on cryptography. The aim of this talk is to explain how it is possible to take over a significant part of the TOR network not to say over the whole network. We have identified two classes of weaknesses in the way Onion routers (Ors) are managed: a first class of weaknesses relates to the way the routes among Ors. It is possible to influence and to force users to use arbitrary Ors and hence control which route they take. A second class of weaknesses relates to the way cryptography is implemented. Bu using malware-based attacks and the concept of dynamic cryptographic backdoors we have succeeded to circumvent the cryptography in place without removing it. We present different possible attack scenarii which are malware-based or not (depending on the scenario considered) that have been experimented and validated on a TOR simulation network of 50 nodes and partially on the real TOR network (as far as it was possible regarding existing laws). We show that it is indeed possible to gain a lot of sensitive information thus bypassing and managing existing cryptographic mechanisms in a very efficient way and to take the effective control over a significant part of the TOR network. The attack is fully dynamic and can be replayed on request. We present an open source library that enable to automate the identification of hidden relay bridges. We propose some modification in the TOR source and protocol in order to prevent those attacks. Demos will be presented to expose the two class of vulnerabilities we exploit. An Internet access is required to make part of the demos on the real TOR network.

We'll cover what we've learned about the mindset of the censor operators (who in many cases don't want to block Tor because they use it!), and how we can measure and track the wide-scale censorship in these countries. Last, we'll explain Tor's development plans to get ahead of the address harvesting and handshake DPI arms races.

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).

Debian Linux Security Advisory 2331-1 - It has been discovered by "frosty_un" that a design flaw in Tor, an online privacy tool, allows malicious relay servers to learn certain information that they should not be able to learn. Specifically, a relay that a user connects to directly could learn which other relays that user is connected to directly. In combination with other attacks, this issue can lead to deanonymizing the user.

Authors: Andrew CaseTags: TorprivacyEvent: Black Hat DC 2011Abstract: Traditional digital forensics encompasses the examination of data from an offline or “dead” source such as a disk image. Since the filesystem is intact on these images, a number of forensics techniques are available for analysis such as file and metadata examination, timelining, deleted file recovery, indexing, and searching. Live CDs present a large problem for this forensics model though as they run solely in RAM and do not interact with the local disk. This removes the ability to perform an orderly examination since the filesystem is no longer readily available and putting random pages of data into context can be very difficult for in-depth investigations. In order to solve this problem, we present a number of techniques that allow for complete recovery of a live CD’s in-memory filesystem and partial recovery of its previously deleted contents. We also present memory analysis of the popular Tor application as it is used by a number of live CDs in an attempt to keep network communications encrypted and anonymous.

Tor's Hammer is a slow post dos testing tool written in Python. It can also be run through the Tor network to be anonymized. If you are going to run it with Tor it assumes you are running Tor on 127.0.0.1:9050. Kills most unprotected web servers running Apache and IIS via a single instance. Kills Apache 1.X and older IIS with ~128 threads, newer IIS and Apache 2.X with ~256 threads.

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).

Debian Linux Security Advisory 2148-1 - The developers of Tor, an anonymizing overlay network for TCP, found three security issues during a security audit. A heap overflow allowed the execution of arbitrary code, a denial of service vulnerability was found in the zlib compression handling and some key memory was incorrectly zeroed out before being freed. The latter two issues do not yet have CVE identifiers assigned.

Debian Linux Security Advisory 2136-1 - Willem Pinckaers discovered that Tor, a tool to enable online anonymity, does not correctly handle all data read from the network. By supplying specially crafted packets a remote attacker can cause Tor to overflow its heap, crashing the process. Arbitrary code execution has not been confirmed but there is a potential risk.

Authors: Marco BonettiTags: privacyphoneEvent: Black Hat EU 2010Abstract: Tor is a software project that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Unfortunately, with the new features of HTML5 and browser built-in geolocation being pushed into the Web2.0 world and on mobile phones and browser, it's becoming harder and harder to keep the users' privacy safe. This presentation will describe the problems which are arising around the use of these new technologies and how they can be (ab)used to attack Tor users. It will also describe where the development is going to protect mobile phone users privacy and let them survive their own devices.
